t Wis., a corporation of Wisconsin Application Febrary zo, 1939, serial No. 257,537 1 claim. (c1. 259-10) i sion` ofy a conveyor means coacting with a mixing chamber which receives the `dairy products for forcing fruits, nuts or other foods into. said chamber from a source to bring about thorough mixing thereof with the dairy products and has coacting therewith an injector disc to force the food into the mixing chamber from the source alsov acting as a check during idleness of the conveyor means to prevent lreverse `flow of the materials from the mixing chamber to the source `over said conveyor means.

With these and `other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be Ahereinafter more fully described and claimed. i I

For a complete understanding of our invention,

reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a top plan view illustrating a feeder or injector constructed in `accordance with our invention. n

Figure 2 is a side elevation illustrating the device. i

Figure 3 is a longitudinal sectional view show-` ing the device.

' Figure 4 is a transverse sectional View taken on the line 4--4 of Figure 3.

Figure 5 is a transverse sectional line taken on the line 5 5 of Figure 3.

j Referring in detail to the drawings,v the numerel 5 indicates anelongated tubular casing in which is located a spiral conveyor 6 provided with a bore to receive an agitator shaft 'I'. One endof the conveyor is in the fornfifof4 a shaft 'I journaled in one` end of the casing and the opposed end of said casing is enlarged .to provide a mixing chamber 8 in which theshaft 1 extends. Theshaft 'I' also extends beyond the shaft 1.

' Agitating fingers 9 are secured on the shaft 'I' for operation in the mixing chamber to mix materials therein. The chamber 8 has an inlet nipple VIIJ extending through the top wall thereof and also it is provided with a substantially conical shaped removable head II equipped with a dis-` u charge nipple I2.

` veyor.

r the inlet nipple.

Non-frozen or frozen dairy productasuch as ice cream, custard and the like from a source may be admitted tothe chamber 8 by way of the inlet nipple .I0 and leaves said chamber by way of the outlet nipple I2.

. 5 The `shaft I of the conveyor 6 extends exteriorly of the casing 5 and has secured thereon a grooved pulley I3 and a pulley I3' is `secured to the agitator shaft I' whereby the conveyor, and the'agitator` may be belted to a `power source (not 10 shown). I

The casing 5 remotely to the mixing chamber 8 Ais cutaway in its tcp' wall and fiared to form a combined mouth and` seat `for a vertically arranged hopper I4 in which foods, such as candy, l5 nuts and the like may be placed to enterthe casing and be taken up by the conveyor and moved vthereby toward the mixing `chamber 8.

The casing 5 on one side thereofzadjacent the mixing rchamber has a slot `and overlying said `20 slot and communicating with the interior of the casing 5 is a housing I5 in which is journaled a disc I6 having on the periphery thereof teeth or projections I1 adaptedto enter the spiralsof the conveyor with two or more teeth thereof always 25 in mesh with the convolutions of the spiral con- The disc vIIiscaused to rotate by the rotation of the conveyor and due to the teeth thereof moving into and out o-f the convolutions j of the conveyor with two or more teeth always in 30 snug fit with said conveyor, the disc andits teeth `act as an injector to force the material carried `by the conveyor into the mixing chamber. Further, the disc andthe teeth thereof act as a check to prevent the material'within the mixing cham-` 35 ber from feeding along the conveyorv in a reverse direction during a period of idleness of said con-- veyor.`

Legs or any other suitable supporting structure,

(not shown) may be provided for thedevice and 40V by varying the speed of rotation of the conveyor I various amounts of material from the hopper may be fed into the mixingchamber forcommingling v with the material fed directly therein by way of A device of the character described and shown 45 inthe drawings is extremely simple in construction, economical to manufacture and maintain in operation and will thoroughly commingle a ina.-

` terial with another material and may be oper-V 50 ated with a minimum amountk of manual effortl and will permit a maximum amount of materials l to be handled and brought togethery withina minimum length of time.

It isbelieved that the, foregoing description,

when taken in connection with the drawings will fully set forth the construction and advantages of this invention to those skilled in the art to which such invention relates, so that further detailed description will not be required.

Having thus described our invention, what Wev claim is:

In adeviceoithe characten set forth, a con,- veyor cylinder irrcluding means adjacent one end for admitting material thereto and provided With a slot adjacent the opposite end thereof, -a mixing chamber formed on the latter-named end ofthe cylinder and including means for admittihg'ma f terial thereto other thanfrom said cylinder provided with a single outlet,- ,a spiral, comIeylorfy ,K extending the full length of'the' cylinder and hav-" v ing a bore arranged axially thereof and extending the full length of said conveyor, a shaft journaled in the bore With one end terminating in the chamber and the other end terminating out- Wardly of the bore and cylinder, belt pulleys secured on the shaft and the spiral conveyor outwardly of the cylinder, a plate closing one end of thecylinder and providinga.- journal for the conveyor, agitating fingers onithe portionof said shaft located Within the chamber, a casing havi .ing a slot matching the slot of said cylinder, and

a toothed disc journaled in the casing and extending through the slots With teeth thereof meshing with said spiral conveyor.
